There can be no doubt that the twentieth century is one of the most remarkable in human history for its previously unprecedented rate of technological advances and scientific discoveries that changed the world, which continues to this day.
In fact, there were so many new gadgets, inventions, and discoveries made in the last century that it’s difficult to pare the list down to just the fifteen (which is why there will be several glaring omissions from my list). However, I think I have managed to whittle it down to those fifteen innovations or technologies that have had the greatest influence on humanity—both positively and negatively. And so, without further ado and in no particular order, here are my nominees for the fifteen greatest inventions/discoveries of the twentieth century:
Top 15 Greatest Inventions:
The duplicate print of the original reduced the handwork and made the world simple by printing and making a photocopy. Started the service with grayscale prints, then later it could develop color images and prints. Having many types of printers and their effects. Xerography may finally supplant traditional printing for the production of books and magazines.
14. The Submarine
The first real submarine was invented in the 1880s, it wasn’t until the twentieth century that the modern submarine came into its own. Today the submarine nearly unlimited range in capacity. The two types of ship: submarines and targets. How useful and effective is the modern submarine?
13. Nuclear Energy
Suddenly humanity had a power source that didn’t pollute, was efficient and practically unlimited, and had the potential to change the planet overnight. Unfortunately, it was a two-edged sword in that this same energy source could be used to create the most destructive weapons in history, threatening human survival with its very presence. While the third world war and, when operated safely, nuclear power plants genuinely are a superb and cost-efficient energy source that has the capacity to power entire cities.
It came before three thousand years ago as the Chinese war weapon and destroyed lives in the 20th century. Most importantly, now they became controllable, which suddenly made them useful both as weapons of war and purposely using some facts. Without the rocket, it is safe to say we cannot visit every planet in our solar system. Rockets also place satellites into orbit around our planet, so without them, no GPS, predict the weather, make international calls or, for the most part, even use our cell phones much of the time.
Antibiotics are playing an essential role in saving people from the disease. After Alexander Fleming discovered penicillin in 1928, it reduces death due to bacterial infection and longer life span. It is also curing of smallpox and typhoid. Antibiotics are treats easily.
Top 10 Greatest Inventions:
Not only did it suddenly make it possible for a person to be heard from hundreds or even thousands of miles away without the use of a wire. Today, it seems to only be useful in the car to keep the driver from falling asleep behind the wheel or as a tool of talk radio designed to disturb the masses. In its day, however, it was every bit as vital to expectations as the television, the computer, the microwave, and the cell phone are to us today.
Without this, the entire world struck. It helps us learn, update the daily news, and make awareness to people, entertainers, and storyteller. Yes, I know it destroys brain cells and renders people emotionally and psychologically damaged, but really, where would we be without the boob tube? It makes unity in the family whenever we eat; we all sitting together and having food. Worse, most of us would have no idea what to do with our time without it, which is probably the saddest commentary of all.
8. The Airplane
From the 20th century, we started flying, shrinking our planet to the point that a person could fly anywhere in the world in a matter of hours. Not only have they made travel quick and safe, but aircraft and airports provide many other services as well: from crop dusting and fighting forest fires to overnight delivery of packages and chasing hurricanes. This saves our time from traveling more time.
7. The Automobile
Until the 20th century, it didn’t become the most practical and reliable source of transportation ever invented, and people the world over still cannot imagine life without them. Most of all, Henry Ford’s assembly-line production style made the automobile affordable and accessible to the average person. It also brought traffic to the market place. The automobile gave everyone personal freedom our forefathers could only dream of, but we live with that and turned entire generations of teenagers into raging redheads.
6. The Personal Computer
Without computers world is none!
Today, of course, they are everywhere, and we have become so dependent upon them that many people almost feel naked without one—someone living because of them nowadays. We use them to keep track of our finances, write books, design logos and sell real estate. Our economy goes down if it goes off from us. Plus, to entertain us with music, movies, and games. Thinking of ancestor without computer those days at this times.
Top 5 Greatest Inventions:
The planet’s first satellite, Sputnik 1, was introduced by the Soviet Union in 1957. Then later, more countries sent their satellites into space. So far, 40 countries have launched 8900 artificial satellites. A satellite is a type of object that is purposely installed in orbit. There are two varieties of the satellite: natural, which contains the moon, and the other is artificial that’s human-made. It has so many reasons to generate satellites; for the planet pictures, star or planetary surface maps, weather forecast, communication, navigation, etc. From 1957, the Space Surveillance Network has been keeping track of all the objects in the Earth’s orbit. Also, it includes three satellite services:
- Fixed services
- Mobile services
- Scientific Research services
4. Microwave Oven
A kitchen appliance that heats and cooks the food with the help of the dielectric heating process. It is also useful and reliable for defrosting. As well, it can function at distinct frequencies. It comprises a transformer, cavity magnetron, capacitor, microcontroller, waveguide, turntable, cooking chamber, and analog or digital control panel.
3. Vacuum Cleaner
Daniel Heis invented the first manual vacuum cleaner model named carpet sweeper in 1860, which collected dust with its rotating brush. After the 19th century, a powered vacuum cleaner with suction was discovered by Hubert Cecil Booth and David T. Kenney. In 1905, Walter Griffiths introduced portable vacuum device for domestic use only. It can be handled by only one person and have a compressor to clean dust through removable, flexible pipes attached with a variety of shaped nozzles. Nowadays, it will take the form of a cleaning head with a handle and garbage collection bag.
2. Mobile Cell Phone
The first time mobile phones were showcased by Motorola in 1973, a portable handphone can connect calls with cell towers over a radio frequency connection. To handle calls or network traffic, multiple towers can be used while the caller or receiver is in motion in the telephone service area. These cellular phones provide several services, including text messaging (SMS), MMS, Email, Internet, wireless communications (Bluetooth), chatting apps, business apps, games, and photography. There are two kinds of Mobile Cell Phones:
- Feature Phone
- Smart Phone
Efficiently achieving the top position on the most incredible inventions is the essential discovery that has given us access to the information period. Obtaining initial popularity from the dot-com bubble outbreak, the World Wide Web has catered to the needs of almost all types of users in the ideal cyber world. Although it is a source for entertainment, education, art, shopping, communication, billing, payment, or research, the Internet can fulfill all of the above and has an infinite number of websites. It is strongly established in our daily lives, and without the internet, we can’t imagine our lives. Our world has become very small due to the internet, and now we can get news from any corner of the world.
